VoltAero Cassio Set To Make First Hybrid Flight
VoltAero will bring its "Iron Bird" to Le Bourget while its Cessna 337-based flight test aircraft is prepared for its first hybrid flights.
As VoltAero evolves its Cassio hybrid aircraft, based on a Cessna 337 airframe, the configuration will include replacing the front engine with boom-mounted motors.

French start-up electric-hybrid aircraft manufacturer VoltAero is preparing to start flight testing its Cessna 337-based "Cassio 1" aircraft with the front engine replaced with propellers driven by electric motors. Meanwhile, it is displaying its "iron bird" mockup incorporating the test hybrid power module at the Paris Air Show (Static A6) and is constructing the Cassio 2 production prototype, which will benefit from the fully validated propulsion system.
